Definitions

  • the invention relates to a contact spring arrangement for actuation through a rocker armature in a miniature relay, with a Carrier made of plastic, in which two contact springs each isolated with their central section in a plane next to each other are anchored, the freely movable end portions of each protrude from the beam on two opposite sides and laterally laterally from their central sections to their longitudinal extent connecting elements from the carrier are brought out.
  • a contact spring arrangement takes place Use, for example, in a relay structure such as the one he uses is described in detail in document EP 0691030 B1.
  • the contact springs connected to the armature serve as center contact elements, which correspond to the Anchor movement optionally with one of its end sections Contact with a fixed contact element arranged underneath give.
  • the side of the center contact springs - to opposite sides - approximately in the area of Armature axis of rotation lead out connection elements serve both for mechanical anchor suspension and storage as also for electrical power supply for the center contact springs.
  • the contact springs embed in the carrier by injection molding
  • the carrier can then be retrofitted using fastening pins or the like can be connected to the anchor; is conceivable but also a separate suspension of armature and contact spring arrangement, the armature movement via slide or the like. is transferred to the latter. Because the end portions of the contact springs for technical reasons, before Overmoulding with their movable contacts or the precious metal contact surfaces must be provided when molding by taking special precautions be made sure that the contact surfaces in the injection mold not be contaminated or damaged.
  • the aim of the present invention is to provide a contact spring arrangement to specify for such a miniature relay with rocker armature, which is particularly easy to manufacture and in which the Contact surfaces are not endangered by the injection mold will.
  • this goal is achieved in that the Contact springs in opposite sides open to each other Plug slots of the carrier are attached.
  • the contact springs are not with the Injection molded material of the carrier, but only afterwards the open slots are inserted or by pinching attached so that the connected to the ends of the contact springs no moving contacts at all in the injection mold reach.
  • the prefabricated contact springs are therefore inserted into the prefabricated carrier with a press fit.
  • the insertion slots are preferably separated by individual ones above and below the respective contact spring perpendicular to the longitudinal axis formed outwardly projecting retaining webs.
  • the retaining webs above the contact spring can face each other those below the contact spring in the longitudinal direction of the Contact spring be offset. This way you can reach in the respective switching directions different resilient Lengths and therefore different spring constants. So can it may be desirable, for example, when lifting the contact springs from their fixed contact a higher spring constant to Bring effect to better tear welded contacts to be able to.
  • the carrier with the holding webs is then particularly favorable manufacture if the holding bars with the intermediate Gaps are matched so that the width of the gaps between the lower holding bars at least the width the opposite upper holding webs and vice versa.
  • the mold division during injection molding the carrier be designed so that this in a two-part shape can be formed without cross slide.
  • FIG. 1 shows a rocker armature 1 with a spring support 2, in the two parallel contact springs 3 and 4 with each on Both ends arranged movable contacts 14 from opposite Pages are inserted here.
  • This anchor with the contact spring arrangement is otherwise part of a relay structure, as shown in EP 0691030 B1. So far referred to this document.
  • the spring support 2 has two spaced-apart central webs 5 and 6, which the carrier with relatively low mass form and the two contact springs 3 and 4 over their entire Isolate length from each other. Perpendicular to its length are lateral of the central webs 5 and 6 Shaped webs, namely webs 7 and 8 each above the contact springs 3 and 4 and retaining webs 9, 10 and 20 below the contact springs. Between the upper holding bars 7 and 8 and the lower holding webs 9, 10 and 20 on the other hand plug slots 11 are formed, into which the contact springs 3 or 4 from the side, i.e. opposite to each other, can be inserted. Can in the area of the holding bridges the contact springs have recesses, not shown, in which locking lugs 12 (only indicated) can snap into place.
  • the holding bars are 7 and 8 or 9, 10 and 20 in the longitudinal direction of the contact springs offset from each other.
  • the holding bars 9, 10 and 20 are closer to the spring ends and thus shorten their springy ends Length when lifting their movable contacts 14 from the associated fixed contacts, not shown. This gives a higher spring constant, which when opening possibly welded contacts is desired.
  • the footbridges 7 and 8 above the contact springs 3 and 4, however, are further from the ends and thus from the moving contacts 14 removed. You enter a when closing the contacts lower spring constant for the contacting force at Structure of the overstroke.
  • connection elements In the middle of the contact springs 3 and 4 are on the side cut-out connecting tab 15 provided in the same level as the contact springs themselves. you go in fastening tabs 16 bent downwards laterally, the connection elements, not shown, in a base the relay attached, for example welded.
  • fastening pins on the carrier 17 integrally formed in corresponding openings 18 of the anchor 1 can be stamped.
  • Figure 2 shows the spring support 2 of Figure 1 in a slightly modified Shape.
  • the holding bars 7 and 8 and 9, 10 and 20 each in their width and in their spacing voted that both the holding bars 7,8,9,10 and 20 as well as the gaps 21 all have the same width b.
  • the wearer as a so-called natural part with a two-part injection mold 22.23 ( Figure 3) without cross slide be made, since the holding bars as well as the slot 11 through the interlocking shape recesses 24 and 25 and projections 26 and 27 formed without undercuts can be.
  • the top two and three lower holding bars instead of the top two and three lower holding bars also other numbers of holding bars be formed. It is essential that the top Holding bridges the gaps between the lower holding bars and face the other way round and that the gaps each at least are as wide as the holding bars opposite. The gaps could also be wider than the holding bars.
